Well I've just completed my first week on the Monash University FODMAP diet using the app to record what I've eaten and the resulting symptoms.
Text Book results baring what I really think was a coincidence 3 days in (suspected bug) especially considering I've had a mad week with a couple of 14 hour shifts.
Unfortunately the details for the last day were not recorded accurately as I never inputed any info before the app's trial finished.
Anyway, its all positive so I'm sticking with it for another week to make sure then will look at reintroducing foods.
